In civil law countries, property right and creditor's right are the two most important components of civil law, which constitute the property right law and creditor's right law respectively. Although both property law and creditor's rights law belong to property law, they are closely related and different, mainly reflected in the fact that the effectiveness of property right is better than creditor's rights. The reasons can be divided into the following categories:

(1) Property Law adjusts the dominant relationship between people and things, that is, the static property relationship. The focus of property law is to protect ownership from infringement, aiming at maintaining the "static security" of property; The focus of creditor's rights is to protect and promote the circulation of property, aiming at protecting the "mobile safety" of property.

(2) Property Law mainly adjusts the ownership of property, which aims to solve the ownership and protection of property in society and directly reflects and protects the social ownership of a country. The Law of Creditor's Rights regulates the circulation of property, aiming at solving the economic problems between specific people (natural persons or legal persons) in society. Compared with the two, it is obvious that the interests of the whole society and the country are higher than the interests of individuals (in a broad sense), and the effectiveness of property rights is of course superior to creditor's rights.

(3) The main content of the Property Law is to confirm the generation, alteration and extinction of various property rights, endow the property rights with dominance and exclusiveness, and usually involve the interests of third parties, which determines that most of the provisions of the Property Law are mandatory and adopt the principle of legalism, and the parties are not allowed to exclude the application of the law according to their own agreements. Creditor's rights are more reflected in the contractual relationship, which has great agreement, and the mandatory effect is higher than the agreed effect, so the effect of property right is naturally superior to that of creditor's rights.

(4) Property law is a property ownership law, mainly about the ownership and protection of social property. Who owns and controls the property directly affects the distribution of social resources and the living security of the whole society, especially land, a limited and scarce natural resource, which is closely related to the public interests of the country and society. Therefore, the property relationship adjusted by the property law often involves the public interests of the third party and society, which is public. The creditor's rights law mostly adjusts the local property relations in society, often involving the interests of two specific relative parties, and its privacy is much stronger than that of the property law. When people live in society, private will must obey public will, and the effect of property right is naturally higher than creditor's right.

The above are the deep-seated reasons why the effect of real right is higher than that of creditor's right.
